40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Chris Harris condemns demonization of Porsche Carrera GT in wake of Walker death

When something bad happens, it's easy to resort to scapegoating. At least for some of us, that seems to be exactly what has happened following the tragic death of actor Paul Walker and racer Roger Rodas, who were killed on November 30 in a Porsche Carrera GT. Even though officials have not yet determined the cause of the crash, that isn't stopping many theories from being put for - theories that include blaming the Porsche supercar. Rather predictably, not only is the CGT's difficult nature getting examined, but indeed, the nature of all high-performance cars is being put under the public's microscope, with some wondering what the need for all the power is.
A Google search of "Porsche Carrera GT" will find no shortage of articles about the razor-sharp handling and outright speed of the CGT. Pistonheads' Chris Harris has a different, insightful take on both the Carrera GT and the nature of all fast cars. He reflects on the matter, ironically, en route to drive the successor to the car that killed Walker and Rodas, the 900-horsepower 918 Spyder hybrid supercar.
We think it's well worth a read, as it makes a number of good points about modern high-performance automobiles and the way they're used. Click over and take a look.

'Latest production version' of Porsche 918 shown off on Twitter

Porsche posted a picture of what it is calling "the latest production version" of the 2015 Porsche 918 Spyder on Twitter. It looks like the gasoline-hybrid supercar is being driven sportively on some California back roads during Monterey Speed Week.
Whatever updates were made to this version aren't visual (except for the paint), as the one Chris Harris drove last spring and another seen hot-weather testing in Nevada both had production bodies. We presume the changes are relatively minor and more than skin deep - perhaps brake calibration, suspension tuning or tweaks to the powertrain - but Porsche didn't release any more information.
The 918 Spyder is Porsche's latest supercar, which will compete with the LaFerrari and the McLaren P1 hybrid supercars. The Porsche may be the underdog of the group when considering horsepower, acceleration, top speed and price, but the 887-horsepower brute has the most advanced hybrid drivetrain of the three.
